Study of some Non-Linear Transforms for ECG Image Compression

Out of the many non-linear transform methods the paper is making use of the (i) EssentiallyNon-Oscillatory cell-average decomposition (ENOCA), (ii) Max-lifting morphological wavelettransform (Maxlift), (iii) Med-lifting morphological wavelet transform (Medlift) and (iv)Morphological Haar wavelet transform (Mhaar) for ECG image compression. This study aims atrecreating the image using inverse transforms after compressing the ECG image by making theuse of the above mentioned transforms. There is an inversely proportionate relationshipbetween image quality and image compression. This study has been undertaken not for thepurpose of quantization and encoding rather an effort is being made to compare the differenttransform methods for ECG image compression.References
